1. Make two sketches of the pendulum: one at its equilibrium position and one at some other position while it is oscillating. Draw vectors on the diagrams for the velocity and acceleration of the pendulum bob, or write v=0 or a=0 if there is no acceleration or velocity.
2. Draw two free body diagrams for the pendulum at the same two positions. Compare the direction of the net force in your free body diagrams to the direction of the acceleration.
3. Sketch three predicted graphs for how the frequency will depend on the properties of the system: frequency vs. mass, frequency vs. amplitude (maximum angle), and frequency vs. string length.
The observed color of an object is not the color of light it absorbs but rather the complementary color, as described by a color wheel such as the one shown here. On this wheel, complementary colors are across from each other. Based on this wheel,..
Also explain the basics of the characteristics of voltaic and galvanic cells.
The reaction that was on the screen when you started and its derivative demonstrate that the change in enthalpy for a reaction, ?H, is an extensive property. Using this property, calculate the change in enthalpy for Reaction 2.
